Systems and methods are provided to log changes to a database on a transaction processing system. A tracking engine identifies an uncompleted transaction to be joined, joins the uncompleted transaction, and collects non-durable attributes of the joined uncompleted transaction. A logging engine makes durable the non-durable attributes by logging the non-durable attributes.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of logging non-durable attributes of an uncompleted transaction to a persistent storage medium, wherein the uncompleted transaction is a transaction processed on a database in a transaction processing system, the uncompleted transaction having a processing path length, the method comprising: (a) using a tracking engine to: (i) identify an uncompleted transaction to be joined, wherein the uncompleted transaction is a transaction that is being executed on behalf of an application or system utility, and wherein joining the uncompleted transaction makes the tracking engine a participant of the uncompleted transaction, wherein the tracking engine identifies the uncompleted transaction to be joined without requiring code modifications to the application or system utility, and without using an intercept library with the application or system utility, (ii) join the uncompleted transaction, wherein joining the uncompleted transaction affects the outcome of the transaction, wherein the tracking engine joins the uncompleted transaction without requiring code modifications to the application or system utility, and (iii) collect non-durable attributes of the joined uncompleted transaction, wherein the collected non-durable attributes became available as a result of the joining of the uncompleted transaction, and wherein the non-durable attributes are related to the uncompleted transaction and are attributes that are not otherwise needed in order to complete a transaction, wherein the tracking engine is a process independent from the application or system utility; and (b) making durable the non-durable attributes of the joined uncompleted transaction by logging the non-durable attributes via a logging engine to the persistent storage medium, wherein the uncompleted transaction in steps (a) and (b) is an audited transaction processed on the database in the transaction processing system.
2. The method of claim 1 wherein the tracking engine joins the uncompleted transaction explicitly.
3. The method of claim 1 wherein the tracking engine joins the uncompleted transaction implicitly.
4. The method of claim 1 wherein one or more of the non-durable attributes have transient values, and step (b) includes making durable at least one of the transient values.
5. The method of claim 1 wherein the collecting and logging of the non-durable attributes require no modifications to the application or system utility.
6. The method of claim 1 wherein at least one of the non-durable attributes of the uncompleted transaction are obtained from the application or system utility.
7. The method of claim 1 wherein the non-durable attributes are made durable by saving the attributes into a database, log file, or report.
8. The method of claim 1 wherein the tracking engine is a resource manager.
9. The method of claim 1 wherein the non-durable attributes of the joined uncompleted transaction include a user ID of a user that started the transaction.
10. The method of claim 1 wherein the non-durable attributes of the joined uncompleted transaction include a program identifier of a program that participated in the transaction.
11. The method of claim 1 wherein the non-durable attributes of the joined uncompleted transaction include a time of day of the transaction.
12. The method of claim 1 wherein the participant is a voting participant.
13. An apparatus for logging non-durable attributes of an uncompleted transaction, wherein the uncompleted transaction is a transaction processed on a database in a transaction processing system, the uncompleted transaction having a processing path length, the apparatus comprising: (a) a tracking engine configured to: (i) identify an uncompleted transaction to be joined, wherein the uncompleted transaction is a transaction that is being executed on behalf of an application or system utility, and wherein joining the uncompleted transaction makes the tracking engine a participant of the uncompleted transaction, wherein the tracking engine identifies the uncompleted transaction to be joined without requiring code modifications to the application or system utility, and without using an intercept library with the application or system utility, (ii) join the uncompleted transaction, wherein joining the uncompleted transaction affects the outcome of the transaction, wherein the tracking engine joins the uncompleted transaction without requiring code modifications to the application or system utility, and (iii) collect non-durable attributes of the joined uncompleted transaction, wherein the collected non-durable attributes became available as a result of the joining of the uncompleted transaction, and wherein the non-durable attributes are related to the uncompleted transaction and are attributes that are not otherwise needed in order to complete a transaction, wherein the tracking engine is a process independent from the application or system utility; (b) a non-transient persistent storage medium; and (c) a logging engine configured to make durable the non-durable attributes of the joined uncompleted transaction by logging the non-durable attributes to the persistent storage medium, wherein the uncompleted transaction in steps (a) and (b) is an audited transaction processed on the database in the transaction processing system.
14. The apparatus of claim 13 wherein the tracking engine joins the uncompleted transaction explicitly.
15. The apparatus of claim 13 wherein the tracking engine joins the uncompleted transaction implicitly.
16. The apparatus of claim 13 wherein one or more of the non-durable attributes have transient values, and step (b) includes making durable at least one of the transient values.
17. The apparatus of claim 13 wherein the collecting and logging of the non-durable attributes require no modifications to the application or system utility.
18. The apparatus of claim 13 wherein at least one of the non-durable attributes of the uncompleted transaction are obtained from the application or system utility.
19. The apparatus of claim 13 wherein the non-durable attributes are made durable by saving the attributes into a database, log file, or report.
20. The apparatus of claim 13 wherein the tracking engine is a resource manager.
21. The apparatus of claim 13 wherein the non-durable attributes of the joined uncompleted transaction include a user ID of a user that started the transaction.
22. The apparatus of claim 13 wherein the non-durable attributes of the joined uncompleted transaction include a program identifier of a program that participated in the transaction.
23. The apparatus of claim 13 wherein the non-durable attributes of the joined uncompleted transaction include a time of day of the transaction.
24. The apparatus of claim 13 wherein the participant is a voting participant.
